Laser powder bed fusion of titanium aluminides: An investigation on site-specific microstructure evolution mechanism

Metal additive manufacturing (AM) improves the design flexibility of titanium aluminides (TiAl-based alloys) as a new class of high-temperature alloys towards widespread applications. In this work, the underlying mechanisms responsible for the site-specific thermal history and grain evolution during...
